Dampers are essential components in HVAC systems, used to control and regulate airflow within ductwork. Various types include butterfly dampers, which use a circular disc to manage airflow, and volume control dampers, designed for precise adjustment of airflow volume. Fire dampers are critical for safety, automatically closing during a fire to prevent the spread of smoke and flames, while backdraft dampers prevent airflow reversal, maintaining system efficiency. Additionally, VAV (Variable Air Volume) dampers adjust airflow based on demand to enhance energy efficiency and comfort, and automatic dampers are operated by sensors or actuators for dynamic control. Multi-blade dampers offer robust airflow control for large-scale systems.

Mixing chambers are used to blend multiple air streams or gases to achieve uniform temperature, pressure, or composition before further processing. They are crucial for ensuring that mixed air or gases meet specific system requirements and provide consistent performance in various applications.
